2 Claims.

This present invention relates to an ink eraser attached to a fountainpen.

The primary object of the invention is the provision of an inkeradicator that is as readily available as the fountain pen with whichit is combined, that will not spill any fluid, but apply the same inmoderation and in the amount desired, that will carry the containerholding the eradicator fluid in a position in which the fluid is readilyapplied or in another position in which no fluid can escape and do anyharm.

It is a further object of the invention to proyide an ink eradicator ofthe type described that is of simple, sturdy and inexpensiveconstruction.

With these objects and other objects that may appear as the descriptionproceeds, in view, this invention consists in certain novel features ofconstruction, combination and arrangement of parts to be hereinaftermore fully described and claimed.

The specific objects of the invention will appear more clearly from thefollowing description read in connection with the accompanying drawings,in which:

Fig. 1 is a side elevation of the body of a fountain pen and alongitudinal diametral section through the cap thereof equipped with anembodiment of my invention;

Fig. 2 is an enlarged longitudinal, diametral section of the upper orouter end of the cap equipped with an embodiment of my invention and online 22 of Fig. 1;

Fig. 3 is a top plan view of the cap equipped with an embodiment of myinvention after the removal of the cover;

Fig. 4 is a detail side view of the sponge and tube carrying the sameboth forming part of the embodiment of my invention.

In the drawings in which like reference characters indicate like orsimilar parts, numeral 2 indicates in general a conventional fountainpen body including a pen p and carryin a cap 3 which includes a clip andencloses only a relatively small upper portion of the pen body andtherefore has a hollow portion there above which is utilized in myinvention. The substantially hemi-spherical end portion 4 of the cap isdetachable from the remainder and provided on its inner side withthreads 5. These are threaded on exterior threads formed on the outerside of a cylindrical flange 6 coaxial with the semi-spherical cover 4and the remaining portion of the cap from which this flange extends andto which it is connected by an inwardl extending flange 1 which definesan exterior shoulder of a width equal to the thickness of the coverwall.

To the inner side of the cylindrical flange is secured the outer side ofthe cylindrical end portion of a well or cup 8 which is closed at thelower hemi-spherical end and has the general shape of a conventionalfountain pen cap. This cup is filled with ink eradictor fluid 9 intowhich extends a tube 10 open at the lower end; the tube also extendsupward through and is secured to the central portion of an end wall IIwhich is fitted in a fluid-tight manner in the upper end portion of thecup. This end wall is preferably fixed to the inside of the cup andsupports a sponge rubber l2 or other spongy substance into which theupper open end of the tube extends. The upper surface of the end wall isnot flush with but slightly below or inward the open end sur face of thecup so that the upper end of the cup forms a flange [3 which surroundsand clamps the sponge rubber. The latter may take various forms,cylindrical, cubical, etc. The preferred form resembles the shape of apyramid, being distinguished therefrom by a ridge 2; taking the place ofthe apex of the pyramid.

In order to replenish the ink eradicator fluid a threaded hole isprovided in the end wall closing the upper end of the cup. A threadedfiller plug [4 notched in the upper end for the insertion of a screwdriver is screwed into the hole and removed therefrom to fill the cupwith ink eradicator fluid.

In order to eradicate ink the cover 4 is removed and the whole peninverted with the result that the sponge is dampened by a small quantityof the fluid flowing down in the tube. The sponge is then applied to theink spot or line to be eradicated. Should the eradicator fluid in thesponge prove insufficient, the latter may again be moistened bysuccessively inverting the pen.

Various modifications and changes are contemplated and may obviously beresorted to, without departing from the spirit or scope of the inventionas hereinafter defined by the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. In an applicator for ink eradicator, an ink eradicator fluid holdingwell adapted to be mounted in a detachable fountain pen cap, conduitmeans, open at both ends, having one end immersed in a fluid containedin the well, said well having an open end provided with a closurethrough which the opposite end of the conduit w a 3 I 4 V 7 meansextends, a sponge secured to the closure UNITED STATES PATENTS V andinto which the outer end of the conduit ber Nam means p and means f e py g a fining 2po3 Stacy 3% 19o7 the well- 1,153,807 MacPherson Sept. 14,1915 2.
